+Adds a custom tag at your cursor location which the generation command looks for and replaces if it is available. The tag can be changed in settings. A tag command and setting should be available for each generation command.
 ### Generate Through The Years
 Uses AI to find Daily Notes from the same date as your current note in years past. Generates a brief summary of this date for each instance of it through the years and places it in your note.
+### Generate Diet Estimates
+Parse your daily journal for food-related lines, and create a `dietEstimates` code-block that estimates your daily calories and macros.
 ## How to Use
-- Enable the plugin in the settings menu and update the plugin settings accordingly
+- Enable the plugin in the settings menu and update the plugin settings accordingly.
 - Open the command palette and search for On This Day I to see the commands.
 - If you want the output to be placed at a certain location in your note, add a placeholder (default is <!OTDI>, can be changed in settings). Run the `On This Day I: Add Placeholder at Cursor` command if you'd like to automatically add a placeholder to your note at cursor location.
 - Run the command `On This Day I: Generate Through The Years` to generate your yearly insights.
+- Run the command `On This Day I: Generate Diet Estimates` to generate a calorie and macro estimates code-block.
 ### OpenAI
 - **This plugin makes a network call to the OpenAI API to generate the journal summaries.**
 - Must have OpenAI API key. See [platform.openai.com](https://platform.openai.com/). Add this key to plugin settings.
